A tainsto make and use the same.

This invention relates t'o improvements in we ther-strips andl more particularly to meta ic weatherstri l l The obct of the present invention is to provide an improved weatherstrip adn. ted to operate with the maximum eiiiclency h wheres door or wi ,"w'and jamh tits en ly and where a door or window and jaiiilr lits loosely.

'A further object of tlie present invention.

is to provide en inproved structure for A. weathenstrps by reason of which the pss- 113951 ,in .the course of the `fo er objects will more articularly apowing detailed.

description.

One sheet of drawings accompanies `this specllcatin as part,thereof, in which like reference characters-indicate similar parts throughout.

' Figure 1 is a fragmentary perspective view of the improved weather-strip;

Fig. 2 is an end view of the strip applied to a door jamh shown in" cross section the door (also in section) fitting loosely;

Fig. 3 is an end elevation of thc strip npplied to a door'jambeshown in cross section where the door lits more snugly;

y acute angle thereto.

In practice beads 3 and 7 are provided,

the former intermediate the plane surfaces,

4 and 6, the latter on the opposite edge of' plane 6 preferably terminating .in an uphmwd lin 8. The plane part l is provided ma. semi are. with s pluralitxcli spaced holes 9 adapted to receive the a 'n nails or screws.

The above specific parts of the improved weather-strip are referably so proportioned that when appli intermediate the door!)l and its jamb thebeeds 5 and 7 will bpth engage the edge of the door in'itsgcloeed position, assuming that the door fits loosely, in which case the double -contact serves to materially steady the door. In the event that the door nfite morcsnngly the strip will be depressed, ss illustrated in Fig. 3, so

that the edge of the door will hc-engaged -only b the head 5 andthe lip 8 wi engage t e jemh. This operation is material, as in the ilexing of metallic weather-stri there is a tendency to lift the parts of t e stri is i lustrated. in Fig. 5 as at 11, said liftnig of the strip permits the passage of dust. By reason of the improved structure above vdescribed1 simultaneously with the lifting of the strip as referred to the lip 8 will contact with the jamb, thus eealing the essa and preventing any air or dust whic mig t en-` ter at the points 11 from paing thedoor. At the same time with the more snu ly fitti door the necessity for'the doub e contac on its edge is eliminated, and with this structure but a single point of contact isy maintained.

The exact angle between the plane surfeces 1' and 4 at lne`2 may, of course,v be varied, and the bead 5 may be merged into plane surface 4 as nt 3, so that the surface will furnish a smooth sliding surface for the door.

ArWhile thc strip has been particularly de scribed with reference to its application to4 doors, its structure has an e ual utility in connection with windows or t e like.

Having described .my invention, what I claiinas new and desire to secure by letters intermediate the fastening membe as An improved weather-strip of'resilient sheet' metal comprising a str1 -bent -longitudinally to form two spaced3 lane faces substantially parallel and thirfiJ plane face intermediate and connecting the same, one of said Aparallel faces -onstituting the attachment face and the other or'ned with a plurality of outwardly directed beads and having its free edge turned outwardly.

M'In testimony whereof I aiix lmy..cs igna-ture.'
